HI
I have read the post earlier, most of the people recommend XPS 8940.
As i watch from youtube, most of the XPS 8940 having cooling problem, if i wanted upgrade how should i do it ya?
I am planning to buy 11700 with 3060TI.

*a middle budget gamer here

Open the case and check the can size. Most likely 80 or 120 or 140mm fans connected to the motherboard. Order a better fan online and swap it. Easy as ABC.

i saaw some video , mention that not all fan compatible as different motherboard size due to dell proprietary mobo.
or Can we just buy a new mobo and new casing to switch over?

xps 8940
1. b460 mobo
2. value ram
3. 500w psu
4. tank casing.. no intake
5. cannot change cooler

take alienware if u wan

Comes with stock 80mm exhaust fan. The rear fan mounting holes can fir 92mm max.

Replaced my stock CPU cooler with Arctic Freezer i13X CO. No need to replace backplate. Mounting set fits just nice with stock backplate.

hows the temp? improving?

Idle 35c, max gaming 76c. No CPU fan noise. Before that, stock cooler max gaming 88c. Loud CPU fan.

Cinebench R20 no difference, CPU still throttle.

Might add an intake fan later. The GPU is still hot.

what fan?casing fan or cpu fan?both of them can change..just need to find compatible one

above lcd is ur sound bar? seems good thing

how high the temp can really go with CPU-Z stress test for 3 minutes? (max reading not current reading)

Same as cinebench test. Temp shoot up to 88c 10 seconds into test and throttle.

i see. i guess need at least 240 water cooling to tame it.

let me share you a trick.

since you have replaced your stock CPU cooler with Arctic Freezer i13X CO,

you can take out the stock CPU cooler fan and replace the rear case fan,

then install the stock rear case fan as intake fan.


fyi, stock CPU cooler fan 59 CFM, stock rear case fan 40 CFM.

Wow sounds like a good plan. Tq for sharing

juz change mobo, psu, casing.. after warranty end

Can't do that unfortunately. XPS 8940 parts are exactly like this G5 except front and side panel.

seem like u dunno wat a pc made off..

those 3 component r swap able... dell proprietary parts are mobo, psu, casing.. this 3 limit the upgrability

n i mean change means change to msi gigabyte those..

Ok

Does anyone know if XPS8940 shipped with 11700 is able to swap the CPU out with a 10400?

I wish to put the 11700 into another rig and put in the 10400 as a replacement for work use. Will the motherboard accept the 10th gen CPU?

never try but should be ok since it's a H470 mobo

Oh..didn't know it's a H470. Thanks for the input man

xps 8940 was shipped out with 10th gen intel.

they just update bios and shipped with 11th gen.

the constant thermal throttling due to cheap cpu cooler is getting into my nerve
planning to upgrade it, but judging from a few videos out there, noctua is the only one that's be able to tame this cpu, but requires some cutting/drilling on the backplate? that's i'm not willing to do
arctic freezer is not bad but still get throttling in cinebench

so anyone out here managed to change the cooler without major modification that will void the warranty?

also anyone added heatsink to the VRM? does it help?

No need a Noctua, if you don't want to spend that much.

I forgot where I saw it in Dell forums, but what does work guaranteed:


1) Vetroo V5 cooler (no modifications needed. Even fan plug works without the annoying F1 at bios fan error beep.

2) Lanshuo 6 pipe cooler (double / triple fan up to you). No need modifications for the mounting. Not sure about the fan connector. Disclaimer, I've ordered one but its piled up in China together with some other parts.

3) The VRM heatsink is sold by Dell. Around RM100. Better buy that than doing guesswork in shopee / lazada. Besides, if you use K variant of the CPUs, your VRMs should have the heatsinks. I'm using the Dell Optiplex 7080MT which has the same VRM layout, that one is confirmed. If you don't use the VRM, you need to short both the top and bottom end of the VRM heatsink screw, or else once you change the CPU to another K variant it'll just spit out a lot of errors not allowing you to boot etc.

4) You can fit a 80mm fan (even the Dell one) to squeeze in between the between the GPU, the GPU bracket and the front chassis. It'll be snug, but some wiggle room. Use zip ties. That way you can introduce airflow to both the PSU and the GPU, but dust may be a problem.




I've been trying to identify the dust filter from Dell, but not sure if its the same kind of dust filter or maybe it isn't.

I had done installed noctua fan and dell fan. Below are the attachments

After install dell fan at lower front case , the temp GPU bring down around 2c

Currently mining at 58c with 59 fan speed . (Side panel and front panel opened). Basically it's a naked pc .
